Description
TECHNICAL FIELD
[0001] The present utility model relates to a system for improving the experience of using a photographing device, and in particular, to a system for adjusting and prompting a photographing device. BACKGROUND
[0002] In the process of image shooting without seeing the screen, such as using a camera to take a selfie, the user can only rely on visual observation to determine his approximate position in the image, and it may take several attempts and errors before he appears in the image at the position he wants. For the user, this is undoubtedly a very bad operation experience. SUMMARY
[0003] To solve the above problems, an object of the present utility model is to provide a system for adjusting and prompting a photographing device, which can tell the user how to appear in the preset position in the image in the process of image shooting without seeing the screen.
[0004] In one aspect, the present utility model provides a system for adjusting and prompting a photographing device, which is suitable for prompting the user how to adjust the photographing device. The system includes an image capturing device and a central control device, wherein the image capturing device is arranged at a position fixed relative to the photographing device and is suitable for shooting a region image; the central control device is electrically coupled to the image capturing device to obtain the region image shot by the image capturing device and determine whether there is a human face image related to a human face in the region image. When there is a human face image in the region image, the central control device determines the content of the control signal according to the size of the human face image in the preset block in the region image, the overlap ratio of the size of the human face image, and the relative position of the human face image and the preset block, and sends the determined control signal to prompt the user how to adjust the photographing device.
[0005] In one embodiment, the above-mentioned system for adjusting and prompting further includes a prompting device electrically coupled to the central control device to receive the control signal from the central control device and prompt the user how to adjust the photographing device according to the control signal.
[0006] In one embodiment, the prompting device includes a plurality of light signals, and each light signal is used to prompt the user to adjust the photographing device in the direction corresponding to the light signal.
[0007] In one embodiment, the control signal sent by the central control device when it is determined that the photographing device does not need to be adjusted will cause the above-mentioned light signals to show the first state, thereby prompting that the photographing device does not need to be adjusted.
[0008] In one embodiment, when the central control device determines that the overlap ratio is lower than a preset threshold, the control signal sent out causes the above-mentioned light to show a second state, thereby indicating that the shooting direction of the camera device is completely deviated from the user's position.
[0009] In one embodiment, when the central control device determines that the overlap ratio is not less than a preset threshold, the control signal sent out causes the photographic device indicated by the light signal to be adjusted in a manner to increase the overlap ratio.
[0010] In one embodiment, the image capture device is a component in a photographic device for capturing images.
[0011] As described above, the camera adjustment prompt system provided by the present invention can generate a prompt message for increasing the overlap ratio based on information such as the overlap ratio and relative position between a facial image and a specific region within the overall image. The user can then adjust the camera device based on the prompt message generated by the adjustment prompt system. Therefore, the camera adjustment prompt system provided by the present invention can allow the user to appear at a predetermined position within the image while the user is capturing an image without being able to see the screen. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 FIG. 4 is a circuit block diagram of an adjustment prompt system for a photographic device according to an embodiment of the present invention.
[0013] Figure 2 FIG2 is a schematic diagram of the appearance of an adjustment prompt system for a photographic device according to an embodiment of the present invention.
[0014] Figures 3A to 3G FIG. 1 is a schematic diagram of an image obtained during shooting by the adjustment prompt system of a photographic device according to an embodiment of the present invention. DETAILED DESCRIPTION
[0015] To ensure clarity for those skilled in the art, it is important to note that the term "electrically coupled" used below refers to enabling electronic signals to be transmitted between two electrically coupled objects. Unless otherwise specified, electronic signal transmission may be wired or wireless, and may be unidirectional or bidirectional.
[0016] Please refer to Figure 1, which is a circuit block diagram of an adjustment prompt system for a photographic device according to an embodiment of the present invention. In this embodiment, the adjustment prompt system 10 for a photographic device includes a central control device 100 and an image capture device 110. The image capture device 110 can obtain a corresponding regional image IMG through a shooting operation, and the central control device 100 is electrically coupled to the image capture device 110 to obtain the regional image IMG from the image capture device 110 and use various image processing methods (for example: a recognition algorithm based on facial feature points, Feature-based Recognition Algorithm) to determine whether there is a facial image related to a face in the regional image IMG. Once it is determined that there is a facial image in the regional image IMG, the central control device 100 will further determine the content of the control signal CTL based on the overlap ratio and relative position between the facial image and the preset block, and finally send out the determined control signal CTL to prompt the user how to adjust the photographic device.
[0017] According to the above content, it can be seen that the factors that determine the content of the final control signal CTL include the overlap ratio between the facial image and the preset block and the relative position between the facial image and the preset block. Therefore, in order to correctly use the regional image IMG captured by the image capture device 110 to adjust the location or shooting angle of the photographic device, the image capture device 110 and the photographic device that the user wants to adjust should maintain a fixed relative position (including relative orientation, distance and line of sight angle). In other words, the image capture device 110 should be set at a fixed position relative to the photographic device that the user wants to adjust. In view of this, when the image capture device 110 and the photographic device exist independently of each other, the user must first set the image capture device 110 at a fixed position relative to the photographic device that the user wants to adjust before using the adjustment prompt system 10. However, it is very troublesome to have to confirm the relative position between the image capture device 110 and the photographic device before using the adjustment prompt system 10 each time. Therefore, a better approach is to choose to fix the image capture device 110 and the photographic device together, or directly use the element of the photographic device itself for capturing images as the image capture device 110. This can eliminate the trouble of having to first confirm whether the relative position between the image capture device 110 and the photographic device to be adjusted meets the originally set conditions.
[0018] Please refer to the following Figure 1 and Figure 2 ,in, Figure 2 FIG. 1 is a schematic diagram of an adjustment prompt system for a photographic device according to an embodiment of the present invention. Figure 1The adjustment prompt system 10 shown is integrated with the photographic device 20, wherein: Figure 1 The central control device 100 shown is disposed inside the photographic device 20, and the image capture device 110 is directly replaced by the lens 210 of the photographic device 20. Furthermore, the adjustment prompt system 10 in this embodiment also includes a prompt device 220 disposed in front of the photographic device 20. The prompt device 220 is electrically coupled to the central control device 100 to receive a control signal CTL from the central control device 100 and prompt the user how to adjust the shooting position or shooting angle of the photographic device 20 according to the control signal CTL. It is worth mentioning that although the prompt device 220 is composed of five light signals 220a, 220b, 220c, 220d and 220e in this embodiment, a person skilled in the art should know that other methods (such as sound) can also be used as a prompt method, so the prompt device 220 is not limited to that provided in this embodiment.
[0019] Next, we will match Figure 2 and Figures 3A to 3G The following describes in detail how the central control device 100 determines the content of the control signal CTL according to the regional image IMG captured by the image capture device 110 .
[0020] exist Figure 3A In the scenario shown, that is, when there is no facial image in the area image 300A captured by the image capture device 110, the control signal CTL sent by the central control device 100 will cause the prompt device 220 to indicate a specific state, for example, all the lights 220a~220e continue to remain in a flashing red state, so as to let the user know that the shooting direction of the photographic device 20 has completely deviated from the user's location.
[0021] exist Figure 3B In the scenario shown, that is, when a facial image 305 exists in the regional image 300B captured by the image capture device 110, the central control device 100 will first calculate the overlap ratio between the facial image 305 and the preset block 310, and then determine the content of the control signal CTL based on the overlap ratio and the relative position of the facial image 305 and the preset block 310. In this embodiment, in order to calculate the overlap ratio between the facial image 305 and the preset block 310, the central control device 100 will obtain the image size of the portion of the facial image 305 within the preset block 310, and divide the obtained image size of the portion of the facial image 305 within the preset block 310 by the size of the facial image 305 to obtain the above-mentioned overlap ratio. Figure 3B In the case shown, since the face image 305 does not enter the preset block 310, the control signal CTL sent by the central control device 100 can be as shown in FIG. Figure 3A In the illustrated scenario, all lights 220a-220e of the prompt device 220 are continuously flashing red, thereby notifying the user that the photographing direction of the camera device 20 has completely deviated from the user's location. Alternatively, in another embodiment, since the facial image 305 is offset to the right of the predetermined block 310, the control signal CTL can be configured to cause lights 220a, 220c, 220d, and 220e to continuously flash red while also causing light 220b to flash green. This allows the user facing the camera device 20 to be informed that the camera device 20 should be moved or rotated more significantly toward the direction indicated by light 220b (i.e., to the user's left) so that the facial image 305 can be brought within the predetermined block 310.
[0022] Please refer to the following Figure 3C .exist Figure 3C In the illustrated scenario, the central control device 100 similarly calculates the overlap ratio between the facial image 305 and the pre-set predetermined block 310 within the regional image 300C, and then determines the content of the control signal CTL based on the overlap ratio and the relative position of the facial image 305 and the predetermined block 310. When the calculated overlap ratio is lower than a predetermined threshold (e.g., 50%), the central control device 100 may determine the content of the control signal CTL to cause the lights 220a, 220b, 220c, and 220e to remain flashing red while also causing the light 220d to flash green. This allows the user facing the camera 20 to be informed that the camera 20 should be moved or rotated more significantly toward the direction indicated by the light 220d (i.e., to the right of the user) to significantly increase the overlap ratio between the facial image 305 and the predetermined block 310. In another scenario, when the calculated overlap ratio is not lower than a preset threshold (e.g., 50%), the content of the control signal CTL determined by the central control device 100 can make the lights 220a, 220b, 220c, and 220e unlit while also making the light 220d alone flash green. This allows the user facing the photographic device 20 to know that the photographic device 20 should be slightly moved or rotated in the direction indicated by the light 220d to increase the overlap ratio between the facial image 305 and the preset block 310.
[0023] Please refer to the following Figure 3DBecause facial image 305 is present in regional image 300D, central control device 100 also first calculates the overlap ratio. When the calculated overlap ratio is below a predetermined threshold (e.g., 50%), central control device 100 determines control signal CTL to cause lights 220a, 220c, 220d, and 220e to remain flashing red while also causing light 220b to flash green. This allows a user facing camera 20 to be informed that camera 20 should be moved or rotated more significantly toward the direction indicated by light 220b (i.e., to the user's left) to significantly increase the overlap ratio between facial image 305 and predetermined region 310. In another scenario, when the calculated overlap ratio is not lower than a preset threshold (e.g., 50%), the content of the control signal CTL determined by the central control device 100 can make the lights 220a, 220c, 220d, and 220e unlit while also making the light 220b alone flash green. This allows the user facing the photographic device 20 to know that the photographic device 20 should be slightly moved or rotated in the direction indicated by the light 220b to increase the overlap ratio between the facial image 305 and the preset block 310.
[0024] Please refer to the following Figure 3E Because facial image 305 is present in area image 300E, central control device 100 also first calculates the overlap ratio. When the calculated overlap ratio is lower than a predetermined threshold (e.g., 50%), central control device 100 determines control signal CTL to cause lights 220b, 220c, 220d, and 220e to remain flashing red while also causing light 220a to flash green. This allows a user facing camera 20 to be informed that camera 20 should be moved or rotated more significantly toward the direction indicated by light 220a (i.e., above the user) to significantly increase the overlap ratio between facial image 305 and predetermined area 310. In another scenario, when the calculated overlap ratio is not lower than a preset threshold (e.g., 50%), the content of the control signal CTL determined by the central control device 100 can make the lights 220b, 220c, 220d, and 220e unlit while also making the light 220a alone flash green. This allows the user facing the photographic device 20 to know that the photographic device 20 should be slightly moved or rotated in the direction indicated by the light 220a to increase the overlap ratio between the facial image 305 and the preset block 310.
[0025] Please refer to the following Figure 3FBecause facial image 305 is included in area image 300F, central control device 100 also first calculates the overlap ratio. When the calculated overlap ratio is lower than a predetermined threshold (e.g., 50%), central control device 100 determines control signal CTL to cause lights 220a, 220b, 220d, and 220e to remain flashing red while also causing light 220c to flash green. This allows the user facing camera 20 to be informed that camera 20 should be moved or rotated more significantly toward the direction indicated by light 220c (i.e., below the user) to significantly increase the overlap ratio between facial image 305 and predetermined area 310. In another scenario, when the calculated overlap ratio is not lower than a preset threshold (e.g., 50%), the content of the control signal CTL determined by the central control device 100 can make the lights 220a, 220b, 220d, and 220e unlit while also making the light 220c alone flash green. This allows the user facing the photographic device 20 to know that the photographic device 20 should be slightly moved or rotated in the direction indicated by the light 220c to increase the overlap ratio between the facial image 305 and the preset block 310.
[0026] Please refer to the following Figure 3G Because the facial image 305 in the regional image 300G completely falls within the coverage of the preset block 310, the calculated overlap ratio reaches 100%. In this case, the central control device 100 can determine that no further adjustments are required to the camera 20 and determine the content of the control signal CTL to cause all lights 220a-220e to flash green simultaneously, thereby informing the user facing the camera 20 that no adjustments to the camera's shooting position or angle are required.
[0027] As can be seen from the foregoing, the photographic device adjustment prompt system provided by the present invention can generate a prompt message for increasing the overlap ratio based on information such as the overlap ratio and relative position between a facial image and a specific region within the overall image. The user can then adjust the photographic device based on the prompt message generated by the adjustment prompt system. Therefore, the photographic device adjustment prompt system provided by the present invention can allow the user to appear at a predetermined position within the image while the user is capturing an image without being able to see the screen.
